I've had nothing but awesomeness with Sprint! Back when basic flip phones were still a thing, I was on Verizon a couple years later I bought a netbook with Verizon service built in. Both purchases I regret - though I like my netbook and still use it - anyways the service I got was overpriced and sub-par for that thing.
The netbook was fine for the first three weeks, I got decent speeds on it. After that though it was all down hill, dropped connections and barely got a signal - I guess they decommissioned a local tower.
As soon as I could I switched to Sprint (AT&T has no service here) and I'm SO glad I did. Actually I went with Virgin Mobile and my Galaxy Victory is on it, currently my second phone with them. About one year after I bought my first phone from them, I got the Sierra 3G/4G USB modem on a 12GB plan, the sprint rep was so nice she actually asked me if I had any questions about my Victory, needless to say I have a very good partnership with my sales rep now.
Just recently I got a Tab 3 strictly for a business tablet - I own my own business and I don't want to keep using my personal stuff for work - I'm really happy with it.
I have been spoiled though because I live about 1/4 mile from a tower. Even on 3G I got about .5-1.50 mbps on my phone and 1.25-2 mbps on my modem on the pre N.V. upgrades. Now on LTE I get speeds of 12-25 mbps on my phone and tablet and about 2.5-3 mbps on my modem.
Bottom line, Sprint has been there for me both for personal, school and for business. Yes there has been hiccups, yes there has been outages, but every carrier does. As soon as the rest of my towers are upgraded, I will be putting my family and I on the Framily plan and getting a Galaxy Mega, Note 3 or Nexus 5.
I am and always will be a Sprint fanboy and supporter.
